To all whom 'it may concern: p

Be it known that I, NATHAN H. LIVING- sToN, a citizen of the United States, residing at Globe,v in -the county 04:' Gila andTerritory of Arizona, have invented certain new and useful iImprovementsin Processes for Reclaiming or Recovering Values from Dust, of which the following is a specification, ref; erence being had therein to the accompany ing-- drawing.

This invention relates vto anew and im-l proved process of recovering values from flue dusts'of smelters, andthe principal obj'ect o'i' the same is to simplifythe known process of ,the same'so as to both cheapen and' facilitate the operation.

So far as is now knowlnithe dust forsmelters 1s ,conveyed to chambers-from which 1t" is taken to bricking machines and pressed into bricks 'and then passed into the' furnace and smeltcd, after which the molten metal is conveyed to the converters where the same is purified.

The present invention aimsI to dispense with the brit-kingoperation and instead con- Veys d ust directly' to the converters.,4

In the accompanying -drawmg a convenient' apparatus for carrying out the 1mproved process has been shown, in which- 1 deslgnates a hopper'ni whlch the (lustl is delivered and gravitates through valveco'ntrolled pipei 2 linto a 4'chamber B into which a valve-controlled -nozzle 4 of `a pipe 5 projects, sai-d pipe 5 being in communication with a high pressure blower (3. vSaid chamber 3 has a pipe connection 7 with alarge pipe 8 of a low pressure blower 9, said pipe 8 discharging into a converter l0.

In this apparatus it will be seen that the nozzle 4 will inject thed'ust from chamber 3 into pipe8 and the pressure within said pipe and tha-tfrom pipe 5 Will convey the dust to the converter where it mixes with the molten matte, and the values therein will be con.-

vertcd into molten metal.v

-It will be seenfrom the foregoing that the improved process greatly simplifies the process of recovering values from flue dust for the reason that the bricking operation is dispensed with and the dust` delivered directlyy to the hopper and then'injected into the converter by means of the blasts from the two blowers. v

That I claim is:

l. The improved process of recoveringr values from flue dust which consists in conveying said dust to a converter to cause the values therein to be melted, and the lother particles of thedust to be mixed with the matte.

2. The improved process Aof recovering values From flue dust which consists in conveyingthe dust to a converter through the injecting action of a high and a' low pressure airkblower v to canse said dust to mix with .the matte ih lthe converter, and reduce the values Vto molten metal, substantial-ly as described.

3. The improved process of recoveringl values t'ron'lifiue dust, comprising the deliv- Ier'v of dust by gravitation to a chamber, then subjecting the delivered dust in said chamber`to distlnct currents of an' under high and low )nessures for conveying the dust t0 the converter, for mixing with' the molten matt/` substantially specified.
